SPECIFICATION 'OImng parti 0f LeterS Patent NO. 685,149, dated October 22, 1901.

Application i'lled May 2S, 1901. Serial No. 62,229. (No model.)

To all whom t may concern:

Be it known that I, JAMES KEITH, a citizen of the United Kingdom of Great Britain and Ireland, residingat 27 Farringdon avenue, London, England, have invented certain new and useful Improvements in Apparatus for Heating and Ventilating, (for which application for patent has been made in Great Britain, No. 20,239, dated November 10, 1900,) of which the following is a specification.

This invention relates to apparatus for heating and Ventilating apartments of buildings; and it has for its object the provision of improved and efcient means whereby airsuitably heated or cold air may be 'so directed into the apartments to be ventilated as to insure positive ventilation in volume in all states of the atmosphere and that Without creating drafts in proximity to the floor or where they may be felt. l

The improved apparatus comprisesa tubular pillar which may reston the floor-level and extend upward to any desired height short of the ceiling or may depend therefrom toward the floor or may take the form of a hollow column extending from floor to ceiling, but having enlarged lateral openings for the discharge of air which is heated by a radiator or radiators in its passage through the pillar or column.

The invention is illustrated by the accompanying drawings, in which- Figures l and 2 are vertical sections of two forms of the heating and Ventilating apparatus.

Referring to Eig. l of the drawings, a fan or blower A is fitted upon a shelf or partition B within the pillar or column B and is driven by an electric motor G or otherwise to draw or blow air through the pillar B from an airshaft H at one end and impel it through the openings B3 into the apartment to be ventilated either directly or against a domed or other cushion. Within the pillar is placed a hot-water or steam heating-radiator C or radiators, preferably of the circular type, for the purpose of suitably warming the air discharged into the apartment. The radiator C within the column B instead of being heated by steam or hot water may be warmed by gas-burners, or a separate form of radiator (suitable for Warming the air by hot air or by gas-burners) may be substituted for the steam or hot-water heated form.

Referring to Fig. 2, the pillar B is formed with a hollow spherical head or dome B2, which is preferably movable or iitted to turn, and in this head one or more lateral openings B3 are formed, each iitted with a fan A tov discharge into the apartment the air warmed in passing around the radiator C or radiators within the pillar B. The fan or fans A may be arranged to direct the air in a lateral and downward direction, the mouth of the lateral opening being suitably inclined for this purpose, especially when the apparatus is fitted in lofty apartments. ln this form of apparatus baffle-plates, such as D, are preferably tted within the dome D2 to break up the flow of the air or prevent it from merely circulating in the dome.

The hollowpillars or columns, of which a number may be fitted within the apartment to be ventilated, may be formed of wood and lined with metal or made wholly or partly of metal, porcelain, or other material and suitably ornamented. The fan employed is preferably of the Blackman silent type, driven by an electric motor and secured upon a wooden seating within the pillar to deaden noise or lessen the transmission of sound.

In the operation of the apparatus fresh air is drawn from a shaft H through the roof or floor F, as the case may be, and through the space surrounding the radiator O within the pillar B and is delivered through the open end of the pillar B or from the fan or fans A in the direction of the arrows into the room at av temperature which may be so regulated by that of the radiator C or radiators and the velocity of the fan or fans A as to maintain a practically uniform temperature within the room in all weathers. The air of the room may thus be kept under a plenum 'or slight pressure, the vitiated air being drawn off by suitable extract-openings. Thus theI fresh air may be blown against the dat ceiling or against the cushion referred to or from the fau or fans in the domed top B2; but when the apparatus is inverted or depends from the roof the air may beblown downward, or the bottom end of the depending tube may be closed and the air discharged through enlarged lateral openings.

Having now described the invention, what the outlet to prevent the air from merely I claim, and desire to secure by Letters Patcirculating in the dome, and lateral openent, isings through which the air is forced by the 15 Apparatus for heating,r and Ventilating fan, substantially as and for the purpose set 5 apartments of buildings, comprising in coinforth.
